The calculator first estimates an hourly rate from your normal weekly fee and booked hours. It values a 15-hour entitlement at up to 570 hours a year, or a 30-hour entitlement at up to 1,140 hours a year. It never deducts more funded hours than the childcare hours entered.
Tax-Free Childcare is then estimated against the remaining childcare bill. The government top-up represents 20% of the amount paid to the provider, capped at £2,000 a year for most children. This is the same as the government adding £2 for every £8 a parent deposits.
Because providers can structure funded places differently, the result is a budget—not a quotation. Meals, consumables and optional activities may be charged separately, and a provider's funded hourly value may differ from its private hourly rate.
